In some countries (e.g. UK), gin and tonic is also marketed pre-mixed in single-serving cans.[4] In the United States, most bars "use soda out of a gun that in no way, shape or form resembles quinine water", according to bartender Dale DeGroff.[1] To get a real gin and tonic, DeGroff recommends specifying bottled tonic.[1] Alternatively, one can add tonic syrup to soda water
